摘要

目的：应用组织多普勒成像（TDI）评价充血性心衰（CHF）患者的左室舒张同步性。方法：74例CHF患者和62例正常人进行TDI检查，检测左室12节段心肌舒张早期达峰时间的最大差值和标准差（TE-Dif和TE-SD），代表舒张同步性；以舒张早期二尖瓣频谱峰值与二尖瓣环速度峰值之比（E/E’）代表舒张功能。结果：CHF患者TE-Dif和TE-SD显著延长，E/E’增大。增大的E/E’是TE-Dif和TE-SD的独立预测因子。结论：CHF常合并左室舒张不同步，且与舒张功能减低关系密切。TDI能够准确评价舒张同步性。

Abstract

Objective: To evaluate left ventricular(LV) diastolic synchrony in patients with congestive heart failure(CHF) using tissue Doppler imaging(TDI). Methods: The TDI examination was performed in 74 patients with CHF, and 62 controls. The maximal difference(Dif) and standard deviation(SD) of the time to the peak early diastolic relaxation(TE-Dif and TE-SD) were measured. And the ratio of the early trans-mitral flow velocity and the early diastolic velocity of mitral valve annulus(E/E’) were assessed as diastolic function index. Results: The TE-Dif and TE-SD were significantly longer, and E/E’ was larger in patients with CHF than in controls. And a larger E/E’ was the independent predictor of diastolic synchrony. Conclusions: LV diastolic synchrony is common in patients with CHF. TDI is a useful and reliable technique for detecting diastolic synchrony.
